GEORGE W. DOVER, OF CBANSTON, RHODE ISLAND.

AUXILIARY WINDSHIELD.

Application filed August 2, 1921. Serial No. 489,157.

To all whom it may concern: Be it known that I, 'Gnonen DOVER, a citizen of the United States, residing at Granston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Auxiliary Windshields, of which the following is a specification.

This invention relates to an auxiliary windshield and more particularly to a windshield adapted for use upon automobiles.

One object of the invention is to provide. transparent shield members adapted for use upon automobiles in connection with the main windshield now commonly used on vehicles of this character for preventing the wind from drawing in around the side edges of the-main wind-shield and thus prevent the creation of a draft through the body of the vehicle, or forcreating a draft within the body of the vehicle when driving asmaybe parts being broken away to show the strucdesired, the elimination of the draft through the body of the vehicle or the creation of the same being dependent uponthe angular position of the'auxiliary shield.

'Another object of the invention is to provide an improved mounting for the transparent shield section whereby the same may be securely held without danger of being broken by the tension exerted upon the same by the holding means. A further object of the invention isito provide an improved supporting means for the aux1l1ary shleld whereby '11? may be,

readilymoved to any desired position relative to the main windshield and at the same time be held in adjusted position against accidental movement.

Other objects and advantages of the invention relate to improved details of construction and methods of operation, as will be more fully set forth in the detailed description to follow.

Referring to the drawings:

' Fig. 1 is an elevational view, certain of the time in detail. Fig. 2' is a top plan view of the auxiliary shield structure, and,

Fig. 3 is a sectional view taken substan tially along the line 33 of Fig. 1.

-. In the embodiment of the invention. illus-- trated herewith, 1O designates the T main windshield of an automobile formed of the usual sections 11 and 12 which are mounted in frames 13 and 1 1, respectively, the frames being carried by the usual upright supports 15.

- The auxiliary shield section 16 of trans supporting element 18 and are adapted to be'turned down into engagement with the upper face of the element 18 to hold the rods against rotation in assembling the shield lower ends of the rods 21 and 22 above the:

structure. Lock nuts 25 are threaded upon'rr the upper ends of-the rods'21 and 22 below the supporting element 17 and similar nuts 26 are threaded upon the rods above the supporting element 17 after the rods have been passed through openings28 formed in the supporting element.

By means of the structure above described movement of the supporting elements towards and from each other is so controlled "as to be directed: along a path. parallel to the.

plane of the shield section and thus cause the pressure exerted upon the shield section by the supporting elements to act in paths parallel to the surface of the shield section.

In this way any tendency to spring or break the shield section such as may be experiencedwhen only one rod is employed is overcome and the shield section is firmly held in place without being subjected to undue strain. a

One or more connecting members may be employedfor connecting theshield section to the upright support, one only of such members being shown in the present inc stance although it is to be'unde rstood that two or more maybe employed if desired.

The jointed connecting member shown herewith for connecting the rod 21 with the upright support 15 comprises a clamping hinge member .30 provided with a pair of hinge sections 31 and 32 rotatably mounted upon a pintle 33, and adapted to be held in clamping engagement; with the upright support 15 by means or a bolt 3% and nut I 35. When the nut 35 is threaded down so as to clamp the hinge sections 31 and 32 to the upright support the sections bind upon the pintle 33 and tend to holdthe same against rotation relative to the hinge sections. v

A block 40 provided with oppositely extending slots' l1 and 42 has formed therein bearings l3 andi communicating with the slots 4:1 and 4L2, respectively, and adapted to' receive the pintle 33 and the rod 21. Bolts 46 and 1-7 I are passed through'the block 40 transversely of the slots'for drawing the endportions oi. the block into binding engagement with the pintle and rod 'whereby a frictional mounting is provided for both the pintle and rod, the frictional V resistance of each bearing being capable of 1 being varied'as desired to increase or decrease the frictional resistance to the rotation" o-f'therod and pintle in the bearings. The provision of the slotted block 'lO'atfords a two-point frictional mounting for I the shield section, whereby the same can be readily swung into any desired posltion relative to the main windshield, while, by-means of the bolts 46 and 47, the frictional resist-' ance to the turning of the rod 01' pintle bolt 47 I i'ntheir bearings may each be varied as desired so as-to enable the apparatus to be so adjusted as to enable the shield member to be rotated either about the rod 21 or-the pintle 33 or both and at the same time frictionally hold the shield member in its adjusted position and prevent its accidental movement therefrom. V

It will be understood that when the bolt 1 46 is tightened to a greater degree than the there will be a tendency for the shield to rotate upon the rod 21in preference to the pintle 33, whilewhen'the bolt 47 is tightened more thanthe bolt 46 the shield will tend to move about the pintle 33 when rotated. In this way, any desired angular position of the shield can be readily obtained "and by properly adjusting the binding'bolts the shield can be moved into or out of the desi'red operative position with out any considerable exercise of care in turning'the same.

A sleeve member 48 is preferably mounted upon the rod'21 and secured thereto by means of a pin 49 passed through the rod and a portion ofthe sleeve member where- 'by the sleeve member is held against move -ment longitudinally of the rod. The sleeve member 48 is located in such a position'upon the rod21 as to be engaged bythe block 40 and thus serve as a"stop" to prevent the L shield memberfrom slidin downwardly as it 'r'ot'at'es about the rod 21 Thus the auxiliary shield member is al ways retained in proper to the main windshield; V V 7 a a The auxiliary windshield may be placed in the position indicated by A in Fig. 2
